Nice saw Bike!
When we cut fibre glass in building bows(archery)as part of the process......being too cheap to invest in diamond blades......"dulling" a blade is inevitable,duh.And it happens rather quickly.We use 14" BS's for this cause.....well we're cheap,the 14's being cheaper to trash.
We never use fancy sharpening equip.Either a handsaw sharpening vise or lengths of steel used in bench vise......both work about the same.There was a learning curve,and this is/wasn't a very scientific approach cause,the blades gonna get trashed again.We just take a cheapo die grinder with whizz-wheels and have at it.With the teeth pointing away,IOWs you stand/grind pulling back twds yourself,blade runnin at at right angle.Once you get a feel for letting the wheel just "ride" the teeth,the process goes pretty quick.
Resharpened blades seem to have a deminishing return of sorts.Meaning they'll never stay sharp as long as the factory grind.....this reduces everytime its sharpen'd.On a wood only blade,I'd expect maybe 3 resharpens,but thats gonna last a loooong time.We never even bother'd with "set" on the glass blades,just keep touchin them up.BW
Those who say it cannot be done shouldn't interrupt the people doing it.
